v BRUSH.

Specification of Letters Patent.

Patented Sept. 26, 1905.

Application filed November 22, 1904. Serial No. 233,810.

following is a specification.

This invention relates to brushes of that class in which the back isprovided with slits located between the rows of bristles for the purposeof-permitting the water and air to pass freely through .the brush-backto the bristles for ventilating and drying the same,

as in tooth-brushes and the like, so that the brush may be readilycleaned and maintained in a clean condition; and. for this purpose'theinvention consists in a brush embodying the back is provided withlongitudinally-extend ing rows of narrow longitudinally-disposed slitsa, which extend through the same between the rows of bristles, theadjacent slits being merged into eachother upon the face of thebrush-back, but separated from each other at the rear of the same bytransverse solid portions 19, as shownv in Fig. 3. The

sides of the longitudinal slits a are parallel, so as to allowsufiicient space for the insertion of the tufts of bristles into theface of the brush-back, and the openings or are arranged in rows or setswhich extend transversely of the brush-back, as shown in Fig.

brushes.

1. Upon the rear of the brush-back the slits a are surrounded byoutwardly-flaring recesses ,.which form funnel or pocket like spaces forfacilitating the passage of water when cleaning the brush to the slitsand along the rows of bristles at the opposite side of the brush. Thesaid pockets 6 also serve after the brush hasbe'en cleaned forpermitting the air to pass throughthe slits, and thereby ventilate thebristles, so as to dry them more quickly than is possible in theordinary very narrow, so that the stock of the brushback, through'whichthe bristles are inserted in the usual manner, is not encroachedupon to too great an extent and the strength of the brush-back is notimpaired as a consequence.

'Heretofore brushes withlongitudinal slits or openings in the back havebeen found to break 'upon dropping the same, as the solid portions ofthe brush-back into which the bristles are inserted, cannot resist theshocks incurred. This is obviated by the improved brush-back, in whichthe face only. is longitudinally 'slitted, While the slits in the rearof the back do not merge into each other, but are separated byintermediate solid portions, by which the brush-body is strengthened atits rear part and is thereby less liable to accidental breakage whilehandling the same.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent ROBERT A. WHITE.
